| dc.description.abstract | Polyporales fungi produce active compounds and secondary metabolites that
have a variety of properties, such as beta glucan. Beta glucan is part of the cell walls
of bacteria, plants, algae, cereals and fungi. Beta glucan has benefits as an
immunodulator and stimulates the immune system. The purpose of this research is to
collect Polyporales fungi specimens in Batu Katak Forest as beta glucan extraction
material and identify the beta glucan content of Polyporales fungi. This research starts
from the collection of Polyporales fungi in the Batu Katak Forest, followed by the
drying process and preparation of simplisia and alkaline extraction and ethanol
extraction. The identification of beta glucan was done using FTIR spectrophotometer.
This study successfully collected 9 species of Polyporales fungi, Panus neostrigosus,
Rigidoporus lineatus, Cerioporus leptocephalus, Ganoderma applanatum, Trametes
pubescens, Ganoderma lucidum, Pycnoporus cinnabarinus, Trametes versicolor,
Earliella scabrosa. There are 6 species that can proceed to the extraction phase due
to having a dry weight of 100 g, namely E. scabrosa, R. lienatus, T. pubescens, G.
applanatum, and T. versicolor. Alkaline extraction results higher yields than ethanol
extraction. Chemical profile using FTIR show that both the alkaline extract and the
ethanol extract of Polyporales fungi and barley have functional groups that constitute
the structure of glucose, including the (-OH) group in the wavenumber range of 3550-
3850 cm1
, the (-CH) group in the wavenumber range of 1340-1470 cm1
, and the (-
O) group in the wavenumber range of 1050-1300 cm1
. Analysis of beta glucan
compounds in alkaline extracts showed that E. scabrosa contained beta 1,3 glucan, P.
neostrigosus contained beta 1,6 glucan, R. lineatus, T. pubescens, T. versicolor
contained beta 1,3 glucan which was branched with beta 1,6 glucan while in ethanol
extracts all extracted samples did not show any beta glucan compounds. The
conclusion of this study obtained 9 types of Polyporales fungi and alkaline extracts of
Trametes versicolor, Rigidoporus lineatus, Trametes pubescens contain beta 1,3
glucan branched with beta 1,6 glucan Eearliella scabrosa contains beta 1,3 glucan
and Panus neostrigosus contains beta 1,6 glucan. | en_US |
